The metro area is expected to see 4 to 6 inches of snowfall - with totals higher in the mountains. Temperatures, so mild and enjoyable Sunday, will drop 40-plus degrees overnight into Monday. From 70 to 30 - or lower, in some places.

CDOT wants to assure you - they're ready for the weather. The question is, are you?

Highway transportation officials would really like you to have snow tires on your car. A lot of people wait until winter to update their worn tires from the summer - it's important to make sure you've got good grip on your car or truck before you hit the roads Monday morning!
